There is no single nationwide license or filing that makes a new business legal. Your obligations depend on where the business operates, what it does, how it is organized, and whether it hires workers. Before taking customers or selling regulated goods, map those facts to state, county, city, federal tax, zoning, and industry rules.
The practical sequence is: define your locations and activities; choose a business structure; clear the name; file the entity if needed; obtain tax identifiers; secure licenses, permits, and zoning approval; set up records and employment systems; then maintain a calendar for renewals and recurring filings. The steps below explain what to check and where the common traps are.

1. Start with the facts that determine your legal checklist
Write down the business’s physical base, every state in which it will have a meaningful presence, the locations from which employees work, where customers are served, and exactly what the business will sell or do. These facts drive entity registration, state tax accounts, local licensing, zoning, and professional or industry regulation.

- Physical location: A storefront, office, warehouse, home office, or mobile operation can trigger different local rules.
- Customer and employee locations: Operating across state lines can create tax and “doing business” questions even when the owner has one headquarters.
- Activity: Food service, construction, childcare, transportation, health services, financial services, alcohol, firearms, environmental work, and other regulated activities may need specialized approvals.
- Premises: A lease, home-occupation rule, occupancy limit, signage rule, or building approval can affect whether the planned location may legally be used.
Use the Secretary of State, state tax department, county or city licensing office, zoning authority, and the relevant industry regulator for the locations and activities you identified. Home-based businesses are not automatically exempt from zoning or permit rules.

2. Choose a legal structure before you file
Structure affects personal-liability exposure, tax treatment, ownership, fundraising, and the amount of recurring paperwork. The U.S. Small Business Administration advises selecting the structure before state registration. Changing later can involve restrictions, new filings, or tax consequences, so complicated ownership, liability, or tax situations warrant advice from a qualified attorney or accountant.
| Structure | Liability and ownership | Tax and fundraising considerations | Formation and ongoing work | Typical fit |
|---|---|---|---|---|
| Sole proprietorship | The owner and business are generally the same legal person, so business debts and claims can reach personal assets. | Business income is generally handled on the owner’s tax return; outside-investor flexibility is limited. | A sole proprietor using the owner’s legal name may not need entity registration, but local licenses, tax accounts, and a trade-name filing may still apply. | One owner testing a low-risk activity who understands the personal-liability exposure. |
| Partnership | Two or more owners share the business under a partnership agreement; liability depends on the partnership form and state law. | Partnership tax reporting and allocations require coordination among owners; raising capital depends on the agreement and structure. | Partnerships generally have state registration obligations where they conduct business, plus an agreement and recurring state filings where applicable. | Multiple owners who want a shared venture and a written allocation of control, profits, and responsibilities. |
| Limited liability company (LLC) | Usually separates company obligations from members’ personal assets when owners respect legal and financial separateness; protection has limits for personal wrongdoing and some guarantees. | Federal tax treatment can vary by elections and ownership; an LLC can accommodate one or more owners and may be less standardized for institutional fundraising than a corporation. | State formation filing, registered agent, operating records, and annual or biennial reports may be required. Fees and deadlines vary by state. | Owners seeking a flexible structure with liability separation and no immediate need for a conventional stock-financing model. |
| Corporation | A separate legal entity with formal governance and ownership represented by shares. | Can support multiple investors and formal equity financing; tax treatment depends on elections and facts. | Articles, registered agent, bylaws, organizational actions, stock records, reports, and possible franchise-tax obligations create more formal administration. | Businesses expecting outside investment, multiple equity holders, or a structure designed for scalable share ownership. |
| Nonprofit corporation | Separate entity status does not itself confer federal tax exemption. | Must satisfy applicable nonprofit and tax-exemption requirements; fundraising and use of assets are restricted by the organization’s purpose and rules. | State formation and continuing reports apply, followed by separate federal and state exemption processes where appropriate. | An organization formed for a qualifying public, charitable, religious, educational, or similar purpose rather than private profit. |
No structure is universally best. Compare the cost of formation and annual reports in your state with the liability, tax, ownership, and financing goals of the actual business.
3. Clear the business name in four separate systems
“Registering the name” can mean several legally independent actions:
- Entity name: The name on an LLC, corporation, partnership, or nonprofit filing. State availability rules apply.
- DBA or trade name: A name used publicly when it differs from the owner’s or entity’s legal name. A county or state may require a filing, renewal, publication, or notice.
- Federal trademark: A separate application and rights system administered by the U.S. Patent and Trademark Office. Search the federal database and relevant state records before investing in branding.
- Domain name: An internet address. Registering a domain does not create trademark rights, and a trademark filing does not guarantee the domain is available.
Check state and local naming rules, search for confusingly similar marks, and confirm that the name is usable in the jurisdictions where you will market. A DBA is a public-facing alias, not a liability shield or ownership entity.
4. File the entity and plan for out-of-state activity
If you select an LLC, corporation, partnership, or nonprofit, file the required formation document with the appropriate state office. Confirm the registered-agent requirement, the official principal address, organizer or incorporator information, ownership records, and any professional-entity restrictions.

After formation, document the organization’s first decisions: adopt an operating agreement or bylaws, identify authorized owners or officers, approve a bank account, issue ownership interests where relevant, and keep the approval in the entity’s records. Do not mix personal and business funds; separate accounts and accurate books help preserve the practical value of limited-liability status.
Foreign qualification
If the business has employees, offices, inventory, repeated in-person work, or another substantial presence in an additional state, ask that state whether “doing business” requires foreign qualification. Registration in the home state does not automatically authorize activity everywhere else. A foreign-qualified entity may owe another state’s annual reports, registered-agent fees, taxes, or local licenses.

Formation fees, annual or biennial report fees, franchise taxes, registered-agent rules, and due dates vary by state and structure. The SBA has described many registrations as costing less than $300, but that is an indicative statement, not a current nationwide price or a guarantee for your filing. Use the current fee schedule and deadline published by the relevant state office.
5. Obtain tax identifiers and build the recordkeeping system
Federal employer identification number
An employer identification number (EIN) is generally required for employers and for certain entity and tax situations. The Internal Revenue Service says to form a state-created LLC, partnership, or corporation before applying for its EIN. The federal EIN application is free through the IRS.
A sole proprietor without employees may not need an EIN in every situation, but a bank, client, payroll provider, or state registration may still request one. Confirm the requirement rather than assuming that “no employees” always means “no EIN.”
State and local tax accounts
Check whether the business must register for sales or use tax, employer withholding, unemployment tax, excise tax, gross-receipts tax, local business tax, or another state or municipal account. The obligation depends on the business activity, locations, customers, and state thresholds. Registration can be required before the first taxable sale or first payroll.
Tax year, books, and records
Select the applicable tax year and accounting method with professional advice when the choice is not straightforward. Establish bookkeeping from the first transaction:
- Record income, refunds, fees, owner contributions, loans, and distributions separately.
- Keep invoices, receipts, contracts, bank statements, payroll records, tax filings, and asset documentation in an organized system.
- Reconcile business accounts regularly and retain records for the periods required by the applicable tax and regulatory authorities.
- Track sales-tax collections and payroll withholdings as amounts held for government agencies, not as ordinary operating cash.
The IRS describes its startup checklist as not all-inclusive, so state and local requirements must be checked separately.
6. Identify licenses, permits, and zoning approvals before opening
Licensing is activity- and location-specific. Search at federal, state, county, and city levels using both the industry and the exact address. The SBA notes that requirements and fees vary with business activity, location, and government rules.
Questions to ask each issuing office
- Is a general business license required, and who issues it?
- Does the activity require a professional, occupational, health, environmental, transportation, or safety license?
- Are there federal approvals for the specific regulated product or service?
- Does the premises need zoning clearance, a certificate of occupancy, a building permit, fire approval, signage approval, or a home-occupation permit?
- Must the license be displayed, and what renewal date, inspection, training, or continuing-education condition applies?
- Is a separate approval required for each location, vehicle, practitioner, or responsible manager?
Do not sign a long lease, advertise an opening date, or take regulated orders until the zoning and licensing offices confirm that the planned use is allowed. A permit application in progress is not the same as an issued permit.

7. Create a separate compliance track before hiring
Hiring adds payroll, workplace, tax, and recordkeeping duties that do not apply to a solo owner. Before the first worker starts, verify whether the person is an employee or an independent contractor under the applicable federal and state tests. A contract label alone does not decide classification.
- Register for required federal and state payroll-tax accounts.
- Set up wage, hour, overtime, meal and rest break, pay-frequency, and recordkeeping procedures required for the work location.
- Complete Form I-9 and collect Form W-4 for each employee as required by federal rules.
- Complete state new-hire reporting and enroll in state unemployment insurance where required.
- Obtain workers’ compensation coverage when the state or circumstances require it.
- Provide required workplace notices, policies, leave, benefits, and safety training for the workforce and industry.
- Use a payroll system that separates gross wages, withholding, employer taxes, reimbursements, and contractor payments.
Headcount, state, job duties, and the worker’s status can change the obligations. Confirm current rules with federal and state labor and tax authorities before extending an offer.

Legal setup is not finished when the certificate arrives. Create one calendar from the registrations and agencies that actually apply to the business. Include:
- State annual or biennial reports, franchise-tax returns, and registered-agent updates.
- Federal, state, and local income, sales, payroll, excise, and other tax filing dates.
- License, permit, inspection, insurance, and professional-renewal dates.
- Payroll deposits, quarterly reports, year-end forms, and required employee notices.
- Lease, occupancy, equipment, vehicle, and safety inspections.
- Changes in address, ownership, responsible manager, business name, or activity that must be reported.
Depending on the business, continuing obligations can also involve advertising claims, copyright and other intellectual-property rules, workplace safety, accessibility, consumer disclosures, privacy, and industry-specific record retention. Assign an owner to each deadline and keep proof of every filing, payment, renewal, and approval.
9. Check beneficial-ownership reporting using the current FinCEN rule
Beneficial-ownership information (BOI) rules have changed. FinCEN’s current BOI page states that its final rule, effective August 14, 2026, exempts U.S. companies from BOI reporting. Certain foreign entities registered to do business in the United States may still have reporting duties, subject to the rule’s exemptions.

Because this area is volatile, determine whether the business is a covered foreign entity and review FinCEN’s current criteria at the time of formation and again when ownership or registration changes. Older startup checklists may still contain the former broad statement that domestic companies must file; do not rely on that outdated language for a current decision.
10. Know when a professional review is worth the cost
A general checklist cannot decide the right structure, tax election, ownership agreement, worker classification, trademark strategy, or regulated-industry permit for a particular business. Obtain an attorney’s review when owners have unequal contributions or control, personal guarantees, valuable intellectual property, regulated services, meaningful liability exposure, or a planned investment round. An accountant or enrolled tax professional can help with entity taxation, multistate filing, payroll, sales tax, accounting method, and record retention.
Professional advice does not replace government filings. Use the issuing agency’s current instructions for forms, fees, deadlines, inspections, and renewals, and keep a dated copy of what was submitted and approved.
